A. J. SMITH WINDOW FRAME Filed Aug. 51, 1940 INVENTO R. filer/we J J/v/TH I ATTORNEY5 Patented Aug. 4, 1942 UNITED STATES PATENT OFFICE WINDOW FRAME Arthur J. Smith, Cleveland, Ohio Application August 31, 1940, Serial No. 355,065

3 Claims.

This invention relates to improvements in window frames, and has reference particularly to means for closing the weight well, for reenforcing the stile and holding it straight, and at the same time providing a wider and firmer support for the finish molding or casing strip at the inside of the frame.

One of the objects of the invention is the provision of means for the purpose-stated which shall be simple in construction, readily applied in the mounting of a window frame in a building structure, and effective both to close the weight well and to supply a relatively wide nailing strip for the finish molding.

Another object is to reenforce the side stiles of the frame against bowing in the plane of the window and hence to maintain constant the window width between stiles and thereby insure easy sliding motion of the sash.

Other objects and features of novelty will ap pear as I proceed with the description of that embodiment of the invention which, for the purposes of the present application, I have illustrated in the accompanying drawing, in which Fig. 1 is a fragmental horizontal sectional view through a portion of a window, its frame and a building wall adjacent the frame.

Fig. 2 is an elevational view of the same with parts broken away to more clearly illustrate the invention.

I have herein illustrated and will describe one side only of a window frame, it being understood that the construction at the opposite side is a duplicate, except as to rights and lefts, of that herein disclosed. A window jamb or side stile constituting part of a window frame is shown at I0. A conventional parting strip H is set into a groove in the stile and with a front stop I2 acts as guiding means for the lower sash H3. The upper sash, not shown, is guided between this parting strip and a blind stop l4. l5 and I6 are wall studs. The outer part of the wall may be of any standard construction, and as illustrated herein consists of sheathing I1, building paper It and siding 19.

The space between stile Ill and stud I5 constitutes a well 9 within which operate the counterbalancing weights 2i] and 2| which are connected by means of cords and pulleys to the upper and lower sash in the conventional manner. The stile I0 is rabbeted along its outer corner on the edge which is directed toward the interior of the building, as indicated at 22, to receive a wood strip 23 which is coextensive with til the stile and to which it is secured at intervals by nails 24 and 24'. It long enough to be fastened to the head and sill of the window frame. Before this strip is applied however there is nailed to its rear surface a strip of thin sheet material 25, preferably metal. Other sheet material, including a combination of metal and plastic, may be employed if desired. This material extends well beyond the outer edge of strip 23, that is far enough to overlap at least a portion of stud I5. It is fastened to the latter by nails 28. Such a strip, particularly when made of metal, possesses a considerable amount of strength in tension and effectively reenforces strip 23 in addition to holding stile I9 against bowing in the plane of the window. Also, of course, it closes off well 9 and prevents any air from leaking into the building through this well. While I prefer to make strip 23 of wood, it will be obvious that it could be constructed of sheet metal formed into a rigid hollow member, and furthermore that such a hollow sheet metal strip could be combined with strip 25, the two strips being formed from a single sheet of metal. Furthermore, the rabbeting of stile It as at 22 is not entirely essential, as the joint with the strip 23 may be effected by other means.

The outer edge of wood strip 23 is eXterio-rly rabbeted, as at 21, so that the ends of lath 28 may be projected into the rabbet in front of the metal strip 25, the lath being secured to the studs in the regular way by nails 29. The lath therefore also forms an abutment for the outer edge of wood strip 23. Plaster 30 may be applied to the lath flush with the forward surfaces of stile l0 and wood strip 23.

Finally a finish molding or casing strip 3| is applied and nailed to the strip 23 as well as to the stile Ill, as indicated by the nails 32, 33 respectively. In prior constructions this molding has been nailed exclusively to the stile I0, leaving the major part of its extent unfastened. Now however a nailing strip 23 is provided which extends out nearly to the edge of molding 3| so that the edge of the plaster is just covered. by the molding. The molding then may be secured in place firmly, and a better and more reliable structure results.

Having thus described my invention what I claim is:

- l. A window frame comprising a side stile, a wall stud cooperating therewith and spaced therefrom to provide a well for counterbalancing weights, a reenforcing strip secured to said stile and projecting laterally therefrom, and a strip of sheet material strong in tension connected with and projecting from the rear surface of said reenforcing strip and protruding outwardly beyond the edge of the reeniorcing strip far enough to close the weight well and be nailed to said stud, said reenforcing strip constituting further a relatively wide and firmly mounted nailing strip to which an inner finish molding may be applied.

2. A window frame comprising a side stile, said stile being rabbeted at its outer corner facing the interior of the building, a wall stud spaced from said stile and cooperating therewith to provide a well for counterbalancing weights, a wood strip set into said rabbet and secured to the stile, and a strip of sheet material strong in tension secured to the rear surface of said wood strip and protruding outwardly beyond the edge of the wood strip far enough to cover the weight well and to be nailed to said wall stud, whereby the stile is reenforced and there is provided a relativelywide and firmly mounted nailing strip to which an 20 inner finish molding may be applied.

3. In a building structure, a window frame comprising a side stile, a wall stud spaced from said stile and cooperating therewith to provide a well for counterbalancing weights, a wood strip secured to the stile and projecting laterally therefrom, and a strip of sheet metal secured to the rear surface of said wood strip protruding outwardly beyond the edge of the wood strip far enough to cover the weight well and to be nailed to the building stud adjacent the window frame, whereby there is provided a relatively wide and firmly mounted nailing strip to which an inner finish molding may be applied, the outer edge of said wood strip being exteriorly rabbeted and overlapping the ends of lath secured to the studding of the building, said lath functioning in combination with said rabbet and. said metal strip to assist in the support of said wood strip.
